The development of electric vehicles, although greatly convenient to our life, but its relative to electric motorcycle a major disadvantage is the lack of range.  Charging every day has almost become a necessary homework for commuters, and some old cars even can only run one-way to work, which makes people very distressed.  

 In the past this problem is unable to eradicate, but we can use careful maintenance, effectively increase the range of electric motorcycle, or delay the battery passivation, so that the storage capacity decreased slowly.  As we all know, electric motorcycle has four big pieces, that is, charger, controller, battery, motor.  So, the main factor that affects its driving mileage, also is inseparable with these four big.  

 Among them, chargers and batteries have a more direct impact, so we should try to choose brand chargers and batteries.  If the new change of electric motorcycle battery also could not run mileage, it means the car have a problem for certain, possible problems appear in the battery cable, battery changes must replace cables together, because for the battery cars are riding two to three years of car, the car for a long time the wind rain, oxidation of be affected with damp be affected with damp, resistance increases, the impact current through, limit the current,  Cause run not far run fast phenomenon.  

 And then the electric motorcycle tire pressure, no matter the load or not, the pressure must be full.  If the air pressure is too low, the friction coefficient between the tires and the ground increases, increasing the rolling resistance, and the controller needs more energy to drive the motor, resulting in a sharp drop in power.  

 Another problem is the brake, brake don't return, can cause drag brake, the problem may be a brake line does not return or rust, it is possible that the brake beam caused by rust do not return, it can cause starting current is too large, affect the battery life mileage, serious when they make the attenuation in advance or damage to the battery or controller.
